Jerry Hairston Jr. “felt a pop” in his left wrist while taking a practice swing in the seventh inning. That’s why he came out of the game.

Hairston said he felt a sharp pain. He has been been having wrist issues on and off since diving for a ball while playing for Cincinnati earlier this season. He disclosed that he had an MRI about 10 days ago and then received a cortisone shot to try and calm some inflammation.

“I’m just hoping it’s some scar tissue breaking up,” he said.

Hairston will have another MRI tomorrow. We should hear more then.

Hairston is hitting only .235 for the Yankees but his value comes in being able to play multiple positions, pinch run, get a bunt down or play late-inning outfield defense. His absence from the postseason roster would be damaging. Not fatally, of course. But the Yankees are better with him than without him.

The Yankees could replace him with Ramiro Pena. But Pena, while versatile, does not have major league experience in the outfield.
